Solar Fan Installation Options There are several types of solar fan Installations; all do different things for different parts of the home. Homes in a tropical climate (Hawaii) will benefit greatly from styles 1&2.

1. Attic only installation – promotes the continued exchange of air in the attic through soffit ventilation only.

2. Thru-ceiling installation. The addition of a duct and grill and installation into the living areas of the home through ceiling or wall will dramatically affect interior air temperature and quality. This is generally recommended for tropical environments or non A/C homes.

3. Gable Mount. Fan housing to be mounted on an existing gable vent with a remote PV panel mounted on the roof above.

• Remote PV Panel installations. All models can be ordered with a remote PV panel. The panel comes equipped with 15 feet of shielded wire. Location instructions should be followed as below. Check Gable Mount instructions for process.

• Thermostat Option For the thermo and fan to work properly the thermo must be wired inline between the positive (red) lead of motor and Positive (red) lead of panel.

Location and Procedure for Self-Flash or Curb Mount Solar Fan Determine the sun’s best exposure location on your roof barring shade (trees, other buildings etc) at 4:00pm in the hottest month of the year. Generally, we recommend a point located centrally on the south, southwest, or west side of the home. At the highest point on the roof, 24”-36” on ctr. off the ridgeline. If multiple fans are required then evenly split the difference. We recommend removing the cardboard cover first to make sure the fan is operational, and then replacing it for safety. SDF-Self Flash Installation Composition Shingle Roofing –retro fit.

1. Measure from the Mid-point on the ridgeline, approximate 24”-36” on center. Mark the spot and drill a hole, using a jig/reciprocating saw, cut a 13 1/2 inch round hole in the roof (Making sure NOT to cut rafter)

2. Fan preparation: a. Remove the top assembly of the solar fan by removing the four (4) S.S. 5/16

sheet metal screws on the base. The top will separate easily from the bottom. This will leave the base assembly separate for installation.

3. Tools required for the next step will be: a flat bar, utility knife, silicone for roofing. Shingle preparation. Simply loosen the course of shingles located at the half-way point of the hole (this may require the removal of some nails) and slide the base assembly up underneath the shingles and notch them as needed. This will require the use of a flat bar. Remove the

base assembly and apply a large bead of silicone on the bottom side of base in the perimeter groove molded into the base. Make sure the Arrow on the fan base is pointed toward the roof peak. Carefully reinstall base back underneath the shingles and align the hole on the decking and the base. Nail the base down in several places and replace the shingles (use roofing adhesive/caulking to reseal the shingles as needed).Make sure to silicone any exposed nail heads. Replace the top vent assembly and the 4 screws. Remove the cardboard over the panel.

SDF-Curb Mount Installation High Profile Roofing Materials Location for fan installation should be the same as above, but great care of installation of this product on tile or any high-profile roofing material should be taken. In fact, we recommend the installation be done by a professional who is experienced with that particular product. Most roof products of this description will have a set course of instruction for any penetrations to be made. That said the process involved for installing our curb mount fan is as follows:

1. Determine proper location (as stated) 2. Build a curb to approx. 19” x 16” O.D. out of 2”x6” materials. Taking into considering

the thickness of your chosen flashing materials. 3. Cut and remove tile to leave a rectangular hole (min 20 x 17) 4. Place curb as template on roof inside tile-cut hole and mark 13 ½ “round hole, then

remove curb. 5. Cut 13 ½” round hole in roof and replace curb and then toenail curb into roof 6. Flash with Lead, copper or other preferred flashing materials 7. Place curb mt. fan over curb and affix with screws

This is only a recommendation and individual roofing professionals may have there own method installations. Please only use a contractor that is trained in your type of roofing. NOTE:

Be advised that if your roof has an existing warranty, installation of this product by any other then those who sold the roof to you may jeopardize any future warranty claim. Please check with your roofer if this is a concern.

Flat Roof Mount Installation Any roof 2 ½ -12 pitch or less, should be treated as a flat roof installation. Construction of a curb should be considered. Potential water pooling and slow run off could over come the vent. Follow steps 1-5 in the Curb mount instructions above. Again this installation may be more suited for professional installer. The Turbine Retro-fit for 12” If there are existing wind turbines on the home, pick the one with the greatest exposure to the south-west sun. Remove the 3-5 screws holding the wind bonnet in place, and remove

the top wind bonnet. Slide the Turbine Retrofit Solar fan over the remaining stack, and use 3-4 self tapping screws (not supplied) to secure. If you’re existing Wind turbine has a 14” diameter you will need to use a 14”-12” reducing duct adapter (available at most roofing and/or HVAC supply stores) The Gable Mount Installation Diagram for Gable Mount Solar fan

• The fan base assembly can be installed between studs or placed over a curb manufactured from 2”x4” (curb dim 19 ¼” X16 1/8”)

• The Remote mount Solar Panel comes equipped with 15ft of shielded wire and it should be mounted on the roof or wall where it will have maximum exposure to the sun. Generally on the south or southwest side of the home. Preferably at or near the peak to prevent shade potentials from affecting the output.

• Drill a small hole in decking large enough for wire to fit through underneath where solar panel will be mounted. Run wire through this hole and to gable fan mounted inside the attic.

• It is recommended to silicone around wire as well as run a bead of silicone around the perimeter of the underneath side of the panel tray and nail to roofing. This will ensure that no water can run under the tray and cause a leak.

• Make sure to silicone nail heads as well. • Wire length up to 50 ft can be added, but use no less then 14 gauge fine stranded

automotive wire, as increased line resistance will occur. • Make sure when you connect wires that the panel is covered to prevent it from producing

power and causing blade to spin. This could be a hazard when making final connections. • You MUST reverse the polarity of the motor for proper gable mount operation. This is

done by connecting the black wire on panel to red on motor and red on panel to black on motor. This reverses the direction of the motor causing it to spin in the right direction for gable use. Make sure to fasten wires so they can not get into the fan blade. We recommend zip tying to the motor bracket assembly. You can now uncover the panel for operation.
